Experimental Procedure
11.A Example 11; Preparation of Epicatechin (4β,8)-Oligomers from Benzyl-Protected Oligomers; A. Preparation of Epicatechin (4β,8)2-Trimer
To a solution of 64.3 mg (33.0 μmol) of bis(5,7,3′,4′-tetra-O-benzyl)epicatechin (4β,8)-dimer in 5 mL of tetrahydrofuran were added 5 mL of methanol, 0.25 mL of water, and 57 mg of 20% Pearlman’s catalyst (Pd(OH)2/C). The mixture was stirred under 1 bar of hydrogen for 80 minutes and filtered over cotton. The filtration residue was washed two times with 10 mL of methanol. The combined filtrates were evaporated, and the residue was taken up in 10 mL of HPLC grade water. The solution was filtered and lyophilized to yield 32.4 mg (101%) of epicatechin (4β,8)2-trimer 6H2O as a fluffy, amorphous, off-white solid: [α]D+70.4°, [α]546+84.40 (MeOH, c 2.2 gL-1); (ref. 4c: [α]D+75.20, acetone, c 8.7 gL-1; ref. 4d: [α]578+90°, MeOH, c 2 gL-1; ref. 6: [α]D+76.40, acetone, c 8.6 gL-1; ref. 19b: []578+920, H2O, c 1.9 gL-1; ref. 19k: [α]D+800, MeOH, c 1.6 gL-1); 13C NMR (CD3OD, TMS; δ 60-85 region only) δ 79.73, 77.08, 73.47, 72.94, 66.84; MS (API/ES) m/z 865.4 (100%; calcd for [M-H]-: 865.2), 577.0 (6%), 288.9 (4%).

Use Pattern
Procyanidin C1 CAS 37064-30-5, a complex polyphenolic compound, falls under the larger category of proanthocyanidins which are widely recognized for their potent antioxidant properties. These substances are found in a variety of plants, including fruits, vegetables, nuts, seeds, and bark, playing crucial roles in plant defense mechanisms against pathogens and environmental stressors. Among the diverse array of proanthocyanidins, Procyanidin C1 is particularly notable for its unique structure and significant health-promoting potentials.
Chemically, Procyanidin C1 is a trimer, meaning it consists of three flavonoid units linked together. This structural complexity contributes to its strong antioxidant capacity, surpassing that of simpler flavonoids and even some vitamins known for their antioxidant properties, such as vitamin E and C. The antioxidant activity of Procyanidin C1 is essential in neutralizing free radicals, unstable molecules that can cause oxidative stress leading to cellular damage, aging, and various diseases.
The health benefits associated with Procyanidin C1 are vast and have been the subject of numerous scientific studies. Research has shown that it can support cardiovascular health by improving blood circulation, reducing blood pressure, and preventing the oxidation of low-density lipoprotein (LDL) cholesterol, a key factor in the development of atherosclerosis. Moreover, its anti-inflammatory effects are crucial in mitigating chronic inflammation, a root cause of many chronic conditions, including cancer, diabetes, and neurodegenerative diseases.
